Li Sibai listened carefully to this cultivation method, and quickly wrote it down.

He was a little strange, this cultivation method of Dou Qi is completely different from True Qi, it is also to absorb the Qing Qi between heaven and earth, after absorbing the True Qi, pay attention to purification, and cultivate a very pure True Qi for his own use, he needs to consume a large amount of Qing Qi to purify, and it can be used when storing it in the body when fighting.

And although this Dou Qi is also absorbing Qing Qi to cultivate, it doesn't need to go through such a lot of effort, he doesn't seem to pay attention to purity, but to speed. Quickly absorb the clear qi between heaven and earth, and quickly transform it into fighting qi, which will obviously be mixed with a lot of incomplete clear qi, and even the turbid qi between heaven and earth will also absorb some, but this is not important, the important thing is that his transformation speed is so fast that Li Sibai is dumbfounded, and it can be released and used not long after it is absorbed, although the power is not as good as the true qi, but this kind of efficiency is also extremely useful in battle.

Li Sibai realized the beauty of this fighting spirit, and his heart was also full of joy, presumably there are very few people in this world who know the secret of the true qi at the same time, and there are even fewer people who can cultivate at the same time, if these two kinds of qi can coexist harmoniously in their own bodies, then they can make up for each other's shortcomings in the battle in the future, and the rapid improvement of their own strength will definitely play a great role in promoting.

"May I ask the seniors, what is the name of this set of methods for cultivating fighting qi?" asked Li Sibai.

"Well, it's not a secret, this set of cultivation methods is our unique cultivation method of the Tree Spirit Clan, the name is Qi Induction Technique, this cultivation method may not be as effective as those methods of the Demon Clan, but it is more peaceful, and a lot of anger can be filtered out, which is more beneficial to you. ”

Li Sibai frowned, "Senior, what will happen if you absorb too much anger?"

The old tree spirit sighed and said, "If you absorb too much anger, you will go mad and fall into the demon clan." ”

After a pause, he said: "But you're okay, on the one hand, the qi induction technique you cultivate itself does not pursue the maximization of efficiency, it can help you filter out some of the abusive qi, and on the other hand, you have the Xuantian Gong True Qi in your body to protect your body, it can also help you resist a part of the aura, and in the future, when you can completely control the two qi in your body, you will be considered to have started." ”

Li Sibai suddenly realized that although this fighting qi saved his life, it was possible to bring him into the demon clan, and Xuantian Gong's true qi could help him slow down this process, it seems that the two complement each other and are indispensable.

Li Sibai thanked the old tree spirit again and said:

"Senior, I have some sect upgrade pills here, I want to complete a breakthrough in the first layer of Qin's state of mind here, I don't know if it's possible?" Li Sibai didn't think about what the old tree spirit said about Guo Jian, he felt that although this was not a good thing, it was also an internal matter of the Xuantian Sword Sect, and there was no need to take it out for others to see the joke.

The old tree spirit nodded and said, "Okay boy, how many days will it take you?"

"Well, it will take about 5 days, okay?"

"Okay, I'll protect the Dharma for you during this time. ”

"I want it too. Cai Yao also said on the side.

"Okay, then we'll be together. ”

Li Sibai smiled, he was relieved to have these two people in him, he had been waiting for this moment for a long time, although Cai Yao had no attack power, but with the old tree spirit, in this dark forest, it was absolutely safe.

Li Sibai ate something again and took out the peacock blue tourmaline bottle.

The old tree spirit on the side was taken aback when he saw this tourmaline bottle, thinking thoughtfully about something, but did not speak.

Li Sibai's attention was on the next cultivation, and he didn't notice the changes in the old tree spirit.

Li Sibai took out some Xuantian Jade Qing Dan and quickly entered the state of cultivation.

Although he has more than a hundred Xuantian Jade Qing Pills, he is still not sure if it is enough, in this case, Li Sibai absorbs them extremely slowly, he tries his best to digest these Xuantian Jade Qing Pills slowly, and strives not to waste every trace of them, as much as possible to improve their strength, so that they can continue to polish and digest in their bodies, and completely absorb them.

In this way, three days have passed, Li Sibai has absorbed seventy Xuantian Jade Qing Pills, and the speed of his absorption is getting slower and slower, his body seems to have reached a limit, and he is extremely tired of this kind of external energy.

Despite this, Li Sibai didn't want to give up, he knew that this process of absorption itself was also a kind of exercise, constantly impacting his limit state, constantly breaking through, and this kind of training was no less than the training he got in battle.

Li Sibai insisted, a day has passed, this day he has absorbed twenty Xuantian Jade Qing Dan, and he is about to be unable to support it a few times in the middle, at this time, his innate fighting spirit will spread all over his body in an instant, Li Sibai will feel a burst of coldness, extremely comfortable, supporting him to keep moving forward.

On the fifth day, Li Sibai seemed to have broken through a limit, he absorbed twenty-five Xuantian Jade Qing Pills, but at this moment, his consciousness was already a little unclear, his eyes began to become blurry, and he was still muttering something in his mouth, and he couldn't hear it clearly.

The old tree spirit and Cai Yao were thinking about whether to remind him, the five days had already arrived, although he had not yet absorbed all of these Xuantian Jade Qing Pills, but it seemed that his state had reached the verge of collapse!

The old tree spirit has not been idle these days, on the one hand, he is strictly guarding to prevent someone outside from coming in and disturbing Li Sibai, and on the other hand, he has been trying to check Li Sibai's progress, he feels that Li Sibai is getting closer and closer to the upgrade.

So he is also very conflicted at the moment, on the one hand, he doesn't know how long Li Sibai can last, and on the other hand, he can't bear to interrupt Li Sibai.

Li Sibai's state of continuous breakthrough in upgrading is the fastest time to improve his experience, such a golden moment, how can he bear to interrupt, the old tree spirit is hesitating here.

On Li Sibai's side, there seemed to be a phantom in front of him, a man in a blue robe stood in front of him, constantly reminding him to pay attention to his breathing and rhythm with words, although these were all inconspicuous small movements, and after Li Sibai did so, there were unexpected changes.

His breathing was no longer cramped as before, it became more and more gentle, the beads of sweat on his head went down a lot, and his complexion became ruddy.

The old tree spirit was also puzzled when he saw this, how did this kid break through the limit again? It was really a great blessing, how did he know that Li Sibai also had the guidance of a master in his dreams, it seems that this kid is about to be upgraded.

The old dryad thought and couldn't help but laugh.
